title: How order affects the sign test.
abstract: In carrying out the sign test, the order in which the subject receives the treatments may be important. We examine Gart's test and show it is equivalent to a score test under a product binomial model. If equal numbers of subjects receive each treatment order, then we suggest our form of Gart's test rather than the sign test should be used routinely.
